In notifying Russell of the release of the prisoners, Lyons had stated that he would caution the Commander of the ship conveying them that they were "not to be received with honours or treated otherwise than as distinguished private gentlemen[482]." Russell was equally cautious, seeing Mason, shortly after arrival in London, "unofficially at my own house," on February 10, refusing to read his credentials, and after listening to a statement of his instructions, replying that "nothing had hitherto occurred which would justify or induce" Great Britain to depart from a position of neutrality[483]. Russell had already suggested that Thouvenel use the same method with Slidell[484]. This procedure does not necessarily indicate a change in governmental attitude, for it is exactly in line with that pursued toward the Confederate Commissioners before the Trent; but the Trent controversy might naturally have been expected to have brought about an easier relation between Russell and a Southern representative. That it did not do so is evidence of Russell's care not to give offence to Northern susceptibilities. Also, in relief at the outcome of the Trent, he was convinced, momentarily at least, that the general British suspicion of Seward was unfounded. "I do not," he wrote to Gladstone, "believe that Seward has any animosity to this country. It is all buncom" (sic)[485]. Apparently it was beginning to be realized by British statesmen that Seward's "high tone" which they had interpreted, with some justification earlier, as especially inimical to England, now indicated a foreign policy based upon one object only--the restoration of the Union, and that in pursuit of this object he was but seeking to make clear to European nations that the United States was still powerful enough to resent foreign interference. The final decision in the Trent affair, such was the situation in the American Cabinet, rested on Seward alone and that decision was, from the first, for peace.

Nor did Seward later hold any grudge over the outcome. America in general, however, though breathing freely again as the war cloud passed, was bitter. "The feeling against Great Britain is of intense hatred and the conclusion of the whole matter is, that we must give up the traitors, put down the rebellion, increase our navy, perfect the discipline of the 600,000 men in the field, and then fight Great Britain[486]." Lowell, in one of the most emotional of his "Bigelow Papers," wrote, on January 6, 1862:

"It don't seem hardly right, John,
When both my hands was full,
To stump me to a fight, John--
Your cousin, tu, John Bull!
Ole Uncle S., sez he, 'I guess
We know it now,' sez he,
'The lion's paw is all the law,
Accordin' to J.B.,
Thet's fit for you an' me[487]!'"

It was not the demand itself for the release of Mason and Slidell that in the end so stirred America as the warlike tone of the British press and the preparations of the Government. Even after their surrender America was further incensed by British boasting that America had yielded to a threat of war, as in the Punch cartoon of a penitent small boy, Uncle Sam, who "says he is very sorry and that he didn't mean to do it," and so escapes the birching Britannia was about to administer. America had, in all truth, yielded to a threat, but disliked being told so, and regarded the threat itself as evidence of British ill-will[488]. This was long the attitude of the American public.

In England the knowledge of America's decision caused a great national sigh of relief, coupled with a determination to turn the cold shoulder to the released envoys. On January 11, the Times recounted the earlier careers of Mason and Slidell, and stated that these two "more than any other men," were responsible for the traditional American "insane prejudice against England," an assertion for which no facts were offered in proof, and one much overestimating the influence of Mason and Slidell on American politics before secession. They were "about the most worthless booty it would be possible to extract from the jaws of the American lion ... So we do sincerely hope that our countrymen will not give these fellows anything in the shape of an ovation." Continuing, the Times argued:

"What they and their secretaries are to do here passes our conjecture. They are personally nothing to us. They must not suppose, because we have gone to the very verge of a great war to rescue them, that therefore they are precious in our eyes. We should have done just as much to rescue two of their own Negroes, and, had that been the object of the rescue, the swarthy Pompey and Caesar would have had just the same right to triumphal arches and municipal addresses as Messrs. Mason and Slidell. So, please, British public, let's have none of these things. Let the Commissioners come up quietly to town, and have their say with anybody who may have time to listen to them. For our part, we cannot see how anything they have to tell can turn the scale of British duty and deliberation."

This complete reversal, not to say somersault, by the leading British newspaper, was in line with public expressions from all sections save the extreme pro-Southern. Adams was astonished, writing privately: "The first effect of the surrender ... has been extraordinary. The current which ran against us with such extreme violence six weeks ago now seems to be going with equal fury in our favour[489]." Officially on the same day he explained this to Seward as caused by a late development in the crisis of a full understanding, especially "among the quiet and religious citizens of the middle classes," that if Great Britain did engage in war with the United States she would be forced to become the ally of a "slave-holding oligarchy[490]."

Here, in truth, lay the greatest cause of British anxiety during the period of waiting for an answer and of relief when that answer was received. If England and America became enemies, wrote Argyll, "we necessarily became virtually the Allies of the Scoundrelism of the South[491]." Robert Browning, attempting to explain to his friend Story the British attitude, declared that early in the war Britain was with the North, expecting "that the pure and simple rights [of anti-slavery] in the case would be declared and vigorously carried out without one let or stop," but that Lincoln's denial of emancipation as an object had largely destroyed this sympathy. Browning thought this an excusable though a mistaken judgment since at least: "The spirit of all of Mr. Lincoln's acts is altogether against Slavery in the end[492]." He assured Story that the latter was in error "as to men's 'fury' here": "I have not heard one man, woman or child express anything but dismay at the prospect of being obliged to go to war on any grounds with America[493]." And after the affair was over he affirmed: "The purpose of the North is also understood at last; ... there is no longer the notion that 'Slavery has nothing to do with it[494].'"

A few extreme pro-Northern enthusiasts held public meetings and passed resolutions commending the "statesmanlike ability and moderation of Seward," and rejoicing that Great Britain had not taken sides with a slave power[495]. In general, however, such sentiments were not publicly expressed. That they were keenly felt, nevertheless, is certain. During the height of the crisis, Anthony Trollope, then touring America, even while sharing fully in the intense British indignation against Captain Wilkes, wrote:
